You should consider using the Streaming API in conjunction with the REST API to build such a service, it might make things a little easier. Currently there are several obstacles for a large-scale integration with a service that intends to duplicate a desktop application's functionality. The REST API, in part due to rate limiting, and in part due to the nature of polling, doesn't make this particularly easy at small scale, and makes it impractical at large- scale.
As luck would have it, we've been very casually discussing just this sort of integration. Feel free to mail me your requirements and I'll get them to the Platform product manager. -John Kalucki twitter.com/jkalucki Services, Twitter Inc.
