It is a fair criticism, though; the KVM prices are comparable to Xen prices, and in that department, they have me beat for guests smaller than 1024M.[1] And you are right that it is time for me to increase my ram per dollar (and my transit per dollar) to remain in the niche where I live. I'm working on it, and you can be sure that existing customers will get that upgrade before I offer it to new users.

[1]I price things at a flat fee per customer ($4) then a cost per unit of ram ($1 for every 64M ram) - I find that there are many providers that beat me on the low end but that I beat on the high end. This is in part an artefact of my manual processes, (or rather, an artefact of how manual per-user processes altered my pricing choices.)
