I suspect it is hard to do a PhD on a protocol but there is a problem that
has interest me a big and I suspect that DAV might be a small part of the
answer. More and more I various communication devices - cell phones, pda,
pager, computers, IM devices. They deal with various media: short
interactive text, longer text, voice, video, smell-o-vision. And I have all
kinds of rules about who can send me messages when and how they get routed
to me. My company has rules too. I have privacy constraints. Regulatory
bodies have rules and anti privacy constraints. If I block Alice from
sending me email, I probably want to block her from IM too. It's fine to
have rules in just a single email reader but if I want the rules there to
effect all my communications, such as a phone call, I need more. How do I
mange all these rules. How do I merge these rules. How does one device
discover my rules, edit them, then upload them for all my devices. How do
privacy of sender and receiver, and preferences of sender and receiver all
get balanced. How do you make it simple enough for a single user to
understand. How can an agent that watches that I just paged Alice decide to
go and add a temporarily rule to page me if I get an email from Alice. How
can we collect enough statistics to realize that I always send phone calls
from Bob to voicemail so just send them straight there without ringing my
phone. I suspect that answering these hard questions might be able to lead
to some PhD research and it seems very likely the way to transport, edit,
and control the policy information could be DAV.

I'm cool with talk about what sort of research could be done involving
WebDav on this list, but please, please, if we are going discuss the SPAM
things, please, please move it to some other list. Anywhere but my backyard
is fine, may I suggest the DKIM mailing list. I'm sure DAV is a fine
protocol to transfer keys for DKIM, take it to the DKIM list.
