maximum myid?

[Jeremy Stribling]

Can the server id in the myid field be any valid long value?  I'm 
interested in generating, rather than pre-assigning, a unique id for 
every server, so my current plan is to convert the server's IP address 
into a 32-bit integer, and use the decimal, ASCII representation of that 
integer for the myid field.  Can anyone think of a reason not to do 
this?  For example, if the code ever uses the id as an index into an 
array, that would probably be bad.

Thanks,
Jeremy
