I would be very reluctant to make any rules around this, at least until we
have real-world examples of leasing behavior causing significant issues that
can't be dealt with through normal processes.  As long as number resources
are being put to productive use, and the whois database is kept up-to-date
with regards to who's actually using the space, I'd be hesitant to try to
micromanage the arrangements between consenting parties...
