I wasn't ready to announce that I was working on it, but I guess now is as good of a time as any...seeing as davo's code is plastered all over my wall in various notebook pages randomly tacked and covered in sticky notes.
davo was pretty far along with his Online plugin. I ran through the source and it already has basic functionality. Honestly I think the community would like it as is, but davo obviously didn't feel that it was ready yet, so out of respect for him and his work I'm going to patch up a few features he was working on before I release it. Right now it works great over a LAN but I plan on including lag compensation features as well.
It is based on Raknet - and I have spoken to Rakkar about what licensing issues that might entail. Basically, you can use the plugin as much as you want, but if you plan on releasing a major project to the public, you have to go to Raknet's site and accept the independent developer's license - which you do by downloading Raknet. You don't need Raknet to use the plugin, so after that you can delete it. You just have to make sure to accept their license. Raknet was davo's choice, not mine - but it was a good choice. Raknet is very feature rich.
Their license is free, up until you make $50,000, after which you pay royalties. If you're making $50,000 on a Construct game, I don't think you'll mind. The license also stipulates that you mention Raknet in any readme files, splash screens, or credit screens.
I have no idea how long it will take to reach a releasable state with this - I'm pretty sure I understand what needs to be added and how to add it, but it will take time. I have about four other plugins I'm working on as well as a day job. Luckily I don't have a life though, so development in my off time will be intense. I wouldn't expect it to take more than a month or two.
