So to recap, some problem solving tools worth knowing are:

1. desk-check, actually read, and 'trust but verify'

	talking through a problem often does this, because it 
forces statement of assumptions that may not actually be true, 
as in Stephen's case.  My suspicion of VLAN network  
partitioning just pointed out a place to look closely

2. 'simplify, simplity'

3. binary partition
