Not many of these services are currently known, and they require authentication from the ThereClient in order to operate. From Camel, in forums:
You'll be unable to do pretty much anything there with just your web browser because in order for the ihost to know just who exactly you are, you have to send a ThereAuthentication? HTTP header (which is a base 64 encoded md5 hash of some information including avatar doid and a unix timestamp -- if anyone is interested in figguring out how to reverse this method completely, please contact me). There is also another ("basic') form of authentication for the ihost; it has a seperate http header ("Authorization") and has a value of "Basic " and a base 64 encoded string whose value is a doid with a trailing colon.
If anyone's interested in learning more, here's a hint. =P ik0ns.com/images/thereauthentication.png
