For the record I tried the wifi solution you mentioned and I can
confirm that it does allow you to push data to the card.
If So, this is great news. I have an IP camera ($50 Trio Stealth 4.3" from BestBuy) and my printer is hooked up to a linux box that I can connect to with X11 over ssh from anywhere using my tablet. Now if this EyeFi thing works the only thing left to do is practice knocking prints of the platform using the jog controls ;)
1. The URL of the upload page, once enabled in the config file, is upload.cgi not .cg as I said (typo)
2. It seems that he upload.cgi CREATES files in all upper case, but overwrites in whatever case is there. You could, in theory have one file called PRINTME.x3g, created on the desktop, that you overwrite on demand, for example. I haven't tried this yet.
3. When playing on my Mac, changes made to the card from the upload script are not immediately reflected on the mounted SD card. I am not sure why. If you eject and reinsert then you see the changes. Maybe the OS buffers or caches or something. I am hopeful that the simpler SD card stack on the Makerbot will work since I don't think it really caches anything.
4. There are other keys such as APMODE and WLANSTMODE for use in the config file that make me wonder if you could get this guy to connect to an existing network.
Remote desktop is complicated and annoying. If there is a way to load the file to the sd card through usb, then we'll do that. I'm sure there is.
Currently, I've gota raspberry pi attached to my printer. Wi-Fi should work, but the raspi doesn't probably give enough power for it.

I am very happy with using the Toshiba FlashAIR card to load files to my Sailfish-enabled Makerbot. I haven't ejected the card from the Makerbot for weeks and I've loaded every file over Wifi successfully. It really is a good way to load files to an SD card. I wrote a small python script that uploads the file and then re-downloads it to verify that it was received properly before printing from the SD Card menu.
If one were inclined, they could make a special version of Sailfish that checked the SD card for new files every so often, and if found, start a print on any new files. Maybe using a file numbering scheme and a counter that tracks the last print number. I don't know if the Sailfish SD FAT library supports file writing, but if it did, you could even write a text file back out with the print statistics at the end of the print to confirm the completion of a print job.
I don't think these are the kind of features Dan would be interested in due to file space limits, but its achievable for the motivated firmware hacker.
