The plan is to eventually have a series of languages developed by a community of programmers under the open source framework, and hosted at code.google.com/opensource .  Download the Aug 2011 beta for uCalc Language Builder to see samples of starting code for languages such as BASIC, Tcl, Python, Forth, and more. IMPORTANT: please do not start submitting or sharing just yet. uCalc LB itself still has many changes to undergo first. Meanwhile, if you have suggestions about which specific kind of open source license would be most suitable for these projects, and can explain why, please send e-mail.  If you are an excellent programmer and have solid experience in organizing and contributing to open source projects, please see the Job Opportunities page.
