Thanks for the information Savantji.
My DP is SBI and they don't charge me on per transaction. It's just Rs.350/yr but I haven't purchased any equities recently. That was how it was a yr ago. Besides now they have also provided the easiest facility free of cost recently. DP wise they seem to be good but their brokerage scheme with Motilal Oswal is very bad.
My DP account is with CDSL and some brokers are not in the list of registered DP's in the CDSL site in such a case with they be able to use a dmat account with CDSL.
I didn't quite get what you mentioned about the portable account and POA.
The angel dp charges (on post #7
http://www.traderji.com/equities/31650-demat-its-nuances.html#post345923) seem to be too high Rs.11/txn with angel and Rs.21/txn outside, besides they charge rs.300 AMC and extra if you want easiest service.

What I have learnt from our tax expert diosys is that you need to have 2 different demat accounts if you want to seperate the capital gains tax from business income (trading) using 2 different brokers won't work. The explanation is simply:
you are holding 50 L&T shares from 1-jan-08 and sell them on 1-jan-09 in such a case not tax (long term 1yr for equities) however lets say in sep-08 you saw an opportunity to make a swing trade in L&T and you buy 100 and sell it for 20% profit in a week then your long term tax will become short term tax because in the demat txns you'll see this:
1.Buy 50 LT 1-jan-08
2.Buy 100 LT 1-sep-08
3.Sell 100 LT 7-sep-08
4.Sell 50 LT 1-jan-09
Your sell in 3 will taken as selling the 1 + 50 shares of 2 and the rest 50 shares of 2 sold in 4
