Started a new company today (Hive At Your Home) which Warre was the answer for. I'm going to be maintaining hives in Boston, NE Mass. and Southern NH, people paying for pollination, having a hive, and some honey. I would not be able to do this with a Langstroth for two reasons. (OK they will be modified Warre to easily comply with NH and MA regs on inspection.)
1st: The start-up capital would prevent Langstroth, but as I have lumber already my version of a modified Warre hives are <$10 each.
2nd: A Langstroth or hTBH would require numerous manipulations throughout the year. When there are at scattered out-yards with sometimes only 1 hive a proper Warre approach allows for much less travel as I'll only open them ~3 times a year.
Additionally I'm getting people to adopt hives at community gardens, organic CSA farms, a historic garden, and an educational center through a kickstarter project (online funding donations with rewards.)
So although there will be Langstroths and hTBHs at my house for breeding, the out-yards will all be Warre. Admittedly this model needs both the revenue from getting most of the honey and people paying to have them there, but then again big commercial guys rely on the pollination fees so...
