Your question is ambiguous: do you mean if I now know of anything preventing? 
(no I don't), or if I can imagine anything that could prevent? (yes I can).
<p>
So I'll answer your constituent's instead: Gwendolyn and I have no particular 
duration in mind.  We do intend to stay in office more than two years (Fate 
willing, of course) - we believe we'd only really have found our style and be 
hitting our stride in our second year.  On the other end, I gave up the 
seneschal's position after five years, and that felt about right, and Aquel & 
Johanna are giving up the Coronet after six, and *that* feels about right, so 
five or six years seems likely.  BUT, anyone who comes around after 4 years 
11 months and starts asking impertinent questions will suffer The Displeasure 
Of The Coronet (that's just Kali talking, not Gwendolyn, she'd never say 
anything like that).
