MiniIM is multi protocol supported instant messagingclient. This is based on J2MEand thus targeted on the MIDP2supported platforms(commonly found in the mobile devices). This is inspired by one of such popular software Pidgin(Gaim). The design is concentrated on the protocol level abstraction and an easy way to integrate new protocol implementations. Finally it is open source. You can modify, extend and redistribute the program under the terms of GPL.
MiniIM is instant messaging client. As it's name(Mini IM) implies it is lightweight. It can connect to different servers through different protocol (Note that it does not convert protocols). And it can do it simultaneously. The user needs identifications (and probably password) to connect to remote server. The interface design is unaware of the underlying protocols. Implementing newer protocol is simple here.
