Groove Web Services. Groove Web Services is going to be a Big Deal. I don’t think I’m violating any NDA’s by telling you that John Burkhardt did an in-house demo yesterday in which he took an empty C# project and, in 5 minutes, wrote a complete Windows app that listed his Groove Contacts. Oh, incidentally, another developer was running a command line Linux app, which did something similar. Don’t want to use Windows to use Groove? Get a cheap Windows PC, install Groove, plug it into your LAN, and go hide it in a closet. Better yet, just set up an account on someone elses’ Grooved PC. Build whatever interfaces you really need, out of .NET/Java/Perl/Fortran, and access it from your Mac/PalmPilot/WebTV/Commodore 64. Jon Udell likes GWS. [Webslice]
