YES

Such a bitcoind is what = I called border router in a previous mail. 

Yes, SPV wallets are getting ahead of features, so people will use them = also because on size just does not fit all, but all want to ensure being = on the same trunk of the chain.
Therefore serious user of Bitcoin run a = bitcoind as a border router and connect SPV wallets with higher = functionality to that trusted node(s).

This is what I think the core should focus = on: Being a lightweight superfast consensus building border router and = nothing more. No wallet, no GUI, no RPC calls,
no Payment protocol and the = rest.

Hello,

This is = primarily aimed at developers of SPV wallets.

The recently = reported decrease in number of full nodes could have several reasons, = one of them that less people are running Bitcoin Core for the wallet = because the other wallets are getting ahead in both features and = useability.

It's great to see innovation in wallets, but it's worrying that the = number of full nodes decreases.

It may be that lots of people = would support the network by running a full node, but don't want to go = through the trouble of installing bitcoin core separately (and get = confused because it's a wallet, too).

Hence I'd like to explore the idea of adding an = option to popular SPV wallets, to spin a bitcoind process in the = background. This could be pretty much transparent to the user - it would = sync in the background, the wallet could show statistics about the node, = but is not dependent on it.

In exchange the user would get increased (full node level) security, = as the SPV wallet would have a local trusted = node.

Does this sound like a good = idea?

Is there any way that Bitcoin Core can = help to accomedate this 'embedded' usage? Specific Interfaces, special = builds - maybe add a walletless bitcoind build to gitian - bindings, = dlls, etc?
