First, I recently talked with Paul Nelson at SIL. He thinks that "one button" REAP archiving will be available next spring. It should deposit a whole project in one fell swoop AND create a "homepage" in REAP for the corpus. The "homepage" will display corpus-level metadata (from Project tab) and link to all deposited Sessions.
This is not "reinventing RAMP". At least not anymore than SayMore already did. A motivating issue behind the proposal was that the process from SM to REAP via RAMP required depositors to re-enter some metadata already existing in SayMore while transferring other metadata automatically to RAMP. The proposed changes was meant to correct that, and as we thought through it, we realized that it was just as easy to bypass RAMP since much of the other requested info is not applicable to language documentation corpora.
Second, I was told by someone at U of Hawaii that there is a high-level proposal submitted in Australia, or USA (i.e. NSF), or both, to fund SM development that, from what I understand, would essentially allow SM users to deposit as easily into any major archive as SIL members should be able to do once the new developments are completed. I don't have a lot of details, but it is something I'm expecting to hear more about, and hopefully soon.
