Android acting as a wifi server?

I am working on a few devices that need to send raw data to an android device wirelessly (wifi). The android devices needs to be able to support multiple devices so I figured a server is best. Is there a way to have 开发者_开发知识库the android device act as kind of a router/server access node by producing its own LAN network?

Any pointers appreciated, ~Aedon

Version 2.2 supports running as an accesspoint, which sounds like what you're after.

I believe this was possible in earlier versions if you had gained root access.
