Regarding connecting to various palaces, there is a security limitation built into the Flash Player that prevents you from connecting to any palace that has not explicitly configured their server to allow OpenPalace to connect to it.
Elitepalaces has added the capability to all palaces hosted with them, but this is a step that must be taken by each palace host in order to allow OpenPalace to connect.
The short version is that you must run a separate server application on the same machine that runs the palace server that will publish a "Policy File" that tells the Flash player that it is allowed to connect to it.
If anyone has questions on how to do this, please contact me directly. You can find my contact information at

I do intend to write a tutorial guide on how to accomplish this, but haven't gotten around to it yet. So for now, you may use OpenPalace connect to any palace hosted by Elitepalaces that allows Guests.
Regarding scripts... Iptscrae is a non-trivial feature to implement. I hope to get to it eventually, but there are a lot of other smaller features that I want to burn through before I tackle that one. As far as I'm aware, all prop generator rooms are implemented as Iptscrae scripts, so those would not be able to work with OpenPalace until Iptscrae support is complete. However, Iptscrae is a severely limited and antiquated language that is probably best left in the past. While I would love to support it for compatibility with existing scripts, it is not well suited for future advancements or developments with the platform. I haven't decided yet whether it might be a better use of my time to implement something more powerful and better understood. JavaScript would make a far superior scripting environment for the Palace, because there are an incredible number of people familiar with it. It would be especially good for new people entering the palace community for the first time, because they could leverage a language they already know instead of learning an arcane language that is only good for one thing. Iptscrae is based on the "Forth" programming language, which has been dead for decades and happily long forgotten. It truly has no future.
As for development schedules, I can't make any promises about rapid progress. This is a project that I am working on only in my spare time. I only have a couple hours now and again to put into it, so progress will likely happen fairly slowly. I was able to make substantial progress in the first few weeks of the project, but unfortunately my life has gotten much busier since then.
I also welcome outside contributors. The source code repository is publicly available, and the entire project is released under the GPL open source license. Anyone who is interested in making contributions of code or other development efforts are welcome to contact me.
