Windows XP support ends in April 2014. Android 2.2/2.3 is currently at 28% market share and dropping. There's a point at where you have to drop support - even if you've got laggards. Look at the stats for your sites, find out the percentage of IE users on Windows XP. A quick sampling of 2 popular sites I'm running shows it to be around 2-3% for IE/XP users - I wouldn't call that heavy use, but obviously it's going to be different for every site. Charge higher prices for those wanting a dedicated IP for their site - pass on the costs which you'll be facing due to IPv4 exhaustion. Prioritise the more important sites for dedicated IPs. If the site generates revenue - keep it on a dedicated IP for a bit longer, if not then it can share an IP with SNI.
