TFTP is UDP based with almost no error resilience, I would not expect it to be used over any sort of wireless link. Its mostly used over things like serial ports where you have 100% control over the line at all times and only send small files.

Perhaps it uses UDP broadcasts when sending the name of the currently playing song over wireless? I don't know of anything relating to TFTP...it is perhaps just for testing. It could use TFTP and send the songs in sections...then just doing a hash check and re-requesting it if the chunk is incorrect.
I did grab some wireless packets before, and it does encrypt some things with WEP (or it just send a wrong 802.11 header out?). Currently playing songs are broadcast unencrypted and in plain text (with a custom binary header).
recovery.bin might be modifiable, as it doesn't appear to have a signature. I don't believe it is distributed with the firmware, so it may have not been tried at all.
Bagder:
WEP is unsafe and it should be possible to retrieve the key(s) used, like with airsnort
I would rather expect the TFTP/UDP things to be used for a magic upgrade case or some special service mode or something and not something used in the ordinary system. Is it possible to upgrade this thing over the network?
zivan56:
I would gladly crack the WEP key, but I have no other Zune. It uses some sort of application layer encryption for wireless syncing, so that would probably need to be figured out as well; not to mention MTPZ encryption.
I don't know about firmware updates over wireless, but they are done over MTPZ.
Overall, they got it locked down pretty tight. However, those files on the drive seem like good candidates to start off...

It's a long shot, but has anybody tried asking Microsoft, or some representatives, or even ex-employees, if this is achievable? Or have we passed this stage already?
