simple email crawler / extractor (java preferred)

This project is simple to explain. We are a web design company and we build sites for people. When we build sites, we often put e-mail address in the pages for our clients. We need a way to capture and export those addresses. ( I also want to be able do make this software shareware.) I need software that will crawl any URL string (including standard websites, search engines etc... ) and extract the e-mail addresses on the pages. The software should capture (in addition to the e-mail address) the domain name, user defined keyword(s). Each of these elements should be captured in seperate columns. The program should be: 1. Multi-threaded. Have an option to enter a number (to define the maximum number of addresses to collect from a single site) 2. The software should allow the export of the data in tab-delimited format as a text file (the software should employ a dropdown in the save dialog that appends either ".csv", or ".txt" to the filename.) I also want a demo and registerable version of the software (as follows). DEMO The demo should allow full-featured searching, and you can click on any e-mail address that the software found and it should launch the default mail client, but it should not allow copy and paste or select all or multiple of the list of records returned, it should also not allow exporting the records. When someone clicks the export button, it should alert that the software is not registered and that you must click on the register button to export the software (this dialog should also show the registration price for the software which it should capture dynamically from our web-server.) REGISTERED: The registered version will permit all the features disabled in the demo and will be a yearly license that will use a license key (that we will generate, you do not need to do this part) to activate the enhanced features. The license will expire in 1 year and at that time it must function as a demo, alerting the user that the license has expired. If you have any questions, please ask. We will undoubtedly both have other ideas as this oges on, so I will be flexible and would love to work with a flexible coder. I am open to suggestions if you have an easier way or better way of doing it. Sincerely Timothy ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc.). ## Platform Must work on all versions of Windows after and including 98 (does not need to work on versions of windows that are older than win 98) Additional requirements for Java (if the winning coder develops in java). Java application must work on all platofrms supporting Java, e.g. Mac OS 9, Mac OSX, Win 98, Win XP etc...
