Hi Greg, Yes, it's possible, the LXJS tweetwall ( https://github.com/luismreis/lxjs-tweetwall) app does precisely that for fetching avatars as you can see on https://github.com/luismreis/lxjs-tweetwall/blob/master/lib/image-manager.js .
Currently you have to explicitly destroy the image on the GPU (you can se the code for that on the same file), but steps are being taken to make that work with the GC. Tip: Even if at some point in the future the garbage collector is used to destroy these resources, it will always be more effective/performing to do it by hand.
