One could upload any file type-- within some limits. I used the
16/44.1K example to illustrate how a high-quality copy would be
preserved and a mp3 generated. I'd suggest that any compatible sound
file be accepted from a list member if the required date-site data
info was provided. There would be no need to up-sample a lower
quality file that was uploaded/posted.
Uploading a file to the archive would take the same amount of time as
uploading to one's own server.
I understand that some folks pay step access rates and can only
afford to receive and send emails. I'm not sure how we overcome this.
When I had dial-up (~three years ago) I did my up-loading and
downloading over night. There was no extra charge. There are some
nifty, free scheduling programs that allow you to toss files/urls
into a folder during the day and auto transfer/download them at night.

mp3 seems to be what people are set-up to make and play at the
moment. The compression rate could be selectable, but I'd just go
with a fixed mp3 format to get started. Rob D.
