I think that the notion of leases are very important.  Can you expand on
your thinking here?  I am especially interested in your thoughts on HTTP
caching.  Would you consider that a "leasing" model?

Thanks,

(1) This sounds very principled, but I can't think of a single example
     of this pattern in other successful standards activities. Could
     you, for example, describe how it applies to, say, the process
     of 30 years of evolution in the TCP/IP community?

(2) How would you characterize the addition of support for
     non-HHTP messaging to SOAP and WSDL?

Specifics, please?

I happen to think (personally, not a Sun position) that the present web
architecture made a colossal mistake in not explicitly modelling the
temporal nature of distributed systems state. Something like Jini
leases would go a long way to solving many of the synchronization and
coordination issues that we've wrestled with in various trout-ponds.
