Do you expect many >100MB uploads on WLM 2012?
Uploads larger than 100MB are already possible (for instance, dmcdevit is
doing one tomorrow), but they need the involvement of
someone with shell
access.
Which hasn't been too problematic, given that uploading through HTTP isn't
the most reliable way to do it.
Upload by url is a viable solution for approved outreach projects, it's
likely to be available on 1.20 deployment (not going to happen on 1.19, as
domain limitation (r109562) was reverted). But won't for a random user.
You can advertise that upload of larger files is possible, and direct your
users to an email address. We can manage it when it comes.
