Hi, sorry for the late answer.
Another mobile remote desktop application for J2ME devices is available at: http://www.crystalballmobile.com/. The main difference is that it use a custom image codec reducing the data traffic to ~4 to 7 MB/hour, resulting ~2KB/s. The current version is supporting only GRPS, 3G, WiFi, but Bluetooth support can be easily created. If this feature will be requested it will be added in the next version.
