Cheapest VPSes around have 0.5/1 GB of ram at least, and as you are well aware 4mB of data means 1,000,000 (might be of by a factor, I'm kinda too lazy to do the exact math ) data cells, so even if you try and sacrifice memory for a lot of things, you won't end up using more than 40 MB of ram anyhow, thats perfectly acceptable at least for me.
