I've been trying to work around this for some time. The best workflow I've found (likely within this thread) was to use SSH on a remote server, sending files back from textastic to be synced. Not ideal, but it works.

What actually works best (by a long distance) in this scenario is diet coda - the remote copy step is pretty transparent, and the UI integrates the SSH nicely, I have a secure remote machine just to carry me over while waiting for this feature to arrive. Would almost be better off with ssh and Vim, but I'd miss the gestures for scrolling!

Besides, using an ipad wifi and a wifi mode (mifi) isn't easy - SSH use is not comfortable in any low-coverage scenario.

I've encountered "remote Dev" solutions that run on a semi-private server too. Not quite something I'm ready for.

As it happens, I did find something with "git integration" .. Worqshop for ipad integrates with GitHub directly using its APIs (i assume) - therefore circumventing the problem with an on-boarded GPL library. Still not ideal, since I still need a remote server to push to the production branch from.

So, still waiting in hope here... Rooting an android tablet to install Ubuntu and sublime text is looking more and more attractive (but still a long way off) :)

Still holding out for a textastic in-app purchase, Alex!!
