Just a few updates...
The font issue is fixed - there was an issue in one of the files that caused the menu font to not change, which caused problems for some themes. Also, there's been some progress in USB support - apparently both reading and writing now work, but there are still a few problems.

For two people that were testing (gevaerts and rasher) it's been reliable, though there seems to be an issue reading from the MicroSD card. Because of the chance of problems that could occur, I probably won't add it until I test it thoroughly, just to be on the safe side. Apparently, there was a report of it cutting of the last character of all filenames, and hosed the filesystem, so if there was a bug, it could be rather bad.

I haven't had a chance to work on personalized builds today, but it seems that all the information is being saved properly, the verification email is being sent, the builds are being verified without problems, and I'm receiving the verification email. For the most part, I believe I need to integrate it into the site, get automated compiling working, allow users to update the build, and allow users to change the build. Automated compiling would probably be done last, due to the massive amount of time it could take - and whether it will be possible. For now, changing and updating the build could be done by emailing me (I'll set that up either tomorrow or Monday), except that'd also mean that it'd be done manually. Integrating it into the site probably won't be hard. Slap the site design on it and have the downloads tied into the upload script.

Come to think of it, I need to work on the upload script a little. Would it be better to have the link for it http://chrisjs.com/upload, or http://chrisjs.com/download? /upload would make sense for uploading the files, but /download would make sense for those downloading...maybe I'll allow both to work.

In a little over a month, I need to start paying for hosting again (I originally paid for a year, because of a promo code). I've gotten enough money from donations and ads that I should be fine until July, so that hopefully won't be a problem.
