[Strawbale] stucco outside, earthen plaster inside?

[Erica Konrad]

Dear all - I was wondering if there is any problem with plastering the 
interior of my strawbale home with earthen plaster and the exterior with 
stucco. We are in British Columbia in a pretty wet, wind exposed site and I 
would like to cover the exterior with stucco for this reason (won't be doing 
the stucco until the spring, but will work on the interior plaster (with 
heat) over the winter). Does is matter if both sides are different finishes 
in terms of moisture?
Thanks in advance,
Erica
