Convert Windows C# Application to Linux Java Application

Hi, Our application is a Digital Signage Media Player Client. It's main job is to talk to the server via XML-RPC which instructs it which media files to download to a local cache. Once downloaded it communicates with an embedded Adobe Flash Control, passing an XML playlist of the media files it should play. We want to create a Linux (Ubuntu?) version of this application so we can avoid having to buy a windows license for our Media Players. So, the job is pretty straightforward... pretty much copy the code to Java and run it on Linux. Some of the tasks it performs: 1) XML-RPC to the server to download a [login to view URL] file 2) XML-RPC to the server to determine what it should be playing 3) XML-RPC to the server to download a [login to view URL] file 4) Download the files specified in the [login to view URL] file 5) Send [login to view URL] file to Embedded Flash Control 6) Simulate a mouse click on the Embedded Flash Control to make it 'full screen' 7) XML-RPC send status messages to the server 8) XML-RPC respond to requests to reset client, restart machine, download new client, clear local cache etc. So... if you've got experience in converting C# applications... or if you're a java / linux guru and want to build the client from scratch.. get in touch. I should note that we're developers ourselves and could probably spend a week hacking about getting it going. So we're not looking for a software house to come in with a huge quote to get the job done. We'll look at reasonable requests from those people with experience. I imagine 1 - 2 weeks would be plenty and as you've got the existing c# code (and can ask us any questions you need) it should be pretty easy. Thanks
