Two minor observations:
DecodeBase58Check is listed as inline, but isnt actually inlined in the
header.
This makes it both non-present in libbitcoin_common.a and unavailable
to other code that would use libbitcoin_common.a as a library. (bug?)
In general, the hierarchy of tools is poor/weak. for example base58.h could
be a fairly
independent low level math/string library, but it includes caddress, which
requires chainparams, and makes the whole dependency tree quite involved...
Is there an intention that the various internal libraries could/should
be strengthened and heirachicalized such that they would be suitable for
3rd party development of bitcoin related services and tools, or is that not
a goal, and some other project would have to fill such a role ?

The plan is to provide the consensus functionality as a library, the
essential parts that make bitcoin bitcoin.
0.10 will have a basic transaction/script verifier available.
In the version after that, I expect this will be extended to further
utxo set management, but no API has been worked out for that yet.
There are also plans to add a library for transaction signing.
However there is no goal to expose *everything* as a library.
Certainly not wallet- or user interface related functionality.
Specialized utility libraries would fill this purpose better.
See for example https://github.com/bitcoin/libbase58 for base58 processing.

A recent comment on this (I think)...
https://github.com/bitcoin/bitcoin/issues/4564#issuecomment-49558760
Reflecting on an approach from a different but related project, as a
result of an issue discussion in DW, stealth and coinjoin from that
project were broken out as distinct repositories - see:
https://github.com/darkwallet/stealth.js
and
https://github.com/darkwallet/coinjoin.js
installable using npm
I'm probably missing something here, but it seems to me like breaking
things out as distinct repositories might be a good approach. The
question is what would be in a distinct repository or repositories?
Currently if someone is looking at core, everything is seen here:

Sorry for the off-topic but while reading this I like to ask you for
picocoin, see:
https://github.com/jgarzik/picocoin
For a research project I'm looking for a C library to operate some block
chain analysis (parsing raw blocks and transactions). Has anyone of you
experience with picocoin for that? Are there any relevant limitations?

Though I am highly biased :) Compared to cbitcoin, picocoin's library
(libccoin) is valgrind-clean, can parse and index the blockchain, and
supports all core and P2P data structures.
