There are ways how to get around cross-domain security restrictions. Long ago, I have done it myself by a simple server-side proxy here (few lines of PHP):
About Globe Genie optimization. In fact, I implemented it, sent a patch to the author and it's already live there (check the source code). It cuts cross-network locations validity lookups by about 60%.
Here I didn't do proxy, just fetched a complete set of overlay tiles once and stitched them together with a Python script:
It's just a static prebaked lookup map (served from the same domain), though if you really want to have it up-to-date, you could hook up Python script to cron.
All this took few hours (Sunday evening hacking) and was quite fun to do.
