Hi, fun to hear of another Brazilian! (I'm obviously not one, but I mean there have been others posting) > I'd like to know if is it possible to host realXtend in Google Apps > Engine. Ryan was correct in his answer, not out of the box. With some work, it would be possible to host the data services (inventory, assets, users) etc. for an Opensim (what we use as server) grid on the Google app engine, because those are web services. In grid mode the region server (the actual simulator) talks with them with http. Would require porting either the current C# or the PHP impls tor Python or Java which the Google AppEngine supports, and to use the special storage API (seemed SQL like) there. Porting the Simian PHP things to Python might be very easy, wasn't Jeroen already looking into that this week? There seems to be even a reference website to help with that :) http://www.php2python.com/ . Apparently there is also an implementation of PHP in Java which can be run on the AppEngine, http://www.webdigi.co.uk/blog/2009/run-php-on-the-google-app-engine/ . But you'd AFAIK still need to port the database code to AppEngine's API, and the asset etc. service codes are almost nothing but the db code. Might be easy though. The (current) realtime client connection to the simulator uses UDP which the AppEngine doesn't support, it only allows you to respond to HTTP requests. So using it to host opensim/realxtend regions is pretty much out of the question, at least if you want to sync movement packets quickly. For slower interaction might be possible to use http, and the upcoming websocket stuff is going to be used for movement etc. in Sirikata, but that's still in the future and it's not known whether AppEngine will support it. There is a feature request for websockets in AppEngine and it's not rejected, but in any timeline either: "Web Sockets API", http://code.google.com/p/googleappengine/issues/detail?id=2535 . > Sorry if it is a silly question.. :-) Like they say, there are no silly questions, and I think this was quite an interesting one - thanks for asking and interest :) > João ~Toni -- http://groups.google.com/group/realxtend http://www.realxtend.org To unsubscribe from this group, send email to realxtend+unsubscribegooglegroups.com or reply to this email with the words "REMOVE ME" as the subject.
