We need block explorer and top 100 list.
The sample is here (zimstake):
http://coinia.net/zimstake/getbalance.php?top=100Guy who can make it requests about 0.25 BTC for work and hosting this.
Contact to him is on bottom of that link, so i propose to establish bounty for that work.
EDIT:
he can do standalone top 100 (cheaper option) or top 100 with awesome block explorer (about 0.25BTC)
