Hi nalanthi,
I prefer ASP as well, but was unable to find decent teamspeak query scripts in either ASP & PHP. I started writing my own basic one a while back, by querying the server using telnet commands: http://www.fayaz.ca/ps/ts/
Eventually, someone started an open-source project on SourceForge called TSDisplay, which is what we're using now. It's still in PHP though, so I run the script on a seperate linux server, then grab & parse the output in realtime using ASP on this site.
TSDisplay: http://sourceforge.net/projects/tsdisplay/
If you're running your site on a windows server, I will gladly host a seperate script for you and provide the ASP code.
