"serious number" would be, say 8+ servers.  yes, I would get someone
to help me mess with 8 servers.  the point is simply that most rails
are quite fiddly - it helps a lot to have someone on either side 
to get tab a into slot b.  as you say, en-railing a 1U isn't that 
hard for a single healthy strapping male geek ;)

(also, I agree that the clumsiest level is shoulder-ish high...)
