Home swap or 2-3 month let?

Hi. My family (two adults, one 7 year old) are travelling round East and Southern Africa in 2011. We want to spend a few months in Kenya (I was born there) and are looking for somewhere homely to stay for 2-3 months whilst we explore the country.

Can anyone put me in touch with relevant websites/people? The ones I have found so far are all focussed much more on holiday lettings and we'd rather stay in a home for that length of time. All ideas gratefully received!
