I'm building right now a translator of Object Pascal to ECMAscript. I just need a common run-time library, which I'm building on top of FPC's RTL and the LCL. If someone wants to have a portable application, they just have to use the classes of the Virtual Machine Library (VML, not to confuse with VCL).
Later, the translator will just change the syntax from Object Pascal to the VM's natural language using a template, then compile the application with an open-source or SDK's compiler, and integrate everything with a version of the VML for the target platform. >From the programmer's point of view, it work exactly as an optimal Pascal command line compiler.
