card emulation is officially supported since Android 2.3.7 (?) and is
used by Google Wallet. However, there is no way (unless you use a
modified ROM) to access card emulation capabilities from your own
applications.

I have another question regarding card emulation. Do you know whether
the UICC is physically connected to the NFC controller (SWP) on the
Galaxy Nexus or not?

Actually, that wasn't my question. I know that the implementation of
the Android NFC stack doesn't support card emulation via SWP out of
box. But if you just patch the firmware like on the Nexus S, you will
get the support for SWP. My question is whether the UICC is physically
connected to the NFC controller by means of SWP. You must distinguish
between the NFC controller (PN544) and the secure element of NXP
(smartMX). The PN544 supports SWP, but if there is no wire towards the
UICC on the Galaxy Nexus it doesn't make any sense to modify the
firmware.

Unfortunately, I don't know for sure. I would assume that the SWP pin
is connected to the NFC controller (just as it is the case with the
Nexus S) but I had no chance to test this yet.
Are you interest in investigating this assumption with me? Another
option would be to ask Samsung. That reduces a lot of overhead
regarding compiling, flashing, debugging etc.

I assume that it will be easier to modify the firmware than to get a
definitive answer from Samsung^^. However, testing if SWP is available
should be rather easy (even without firmware modifications) if you
have an SWP-enabled UICC. I expect that SWP will be initialized even
if emulation mode is not switched to the UICC. So I guess you could
just measure the voltage signal on the SWP pin (that's the
communication from CLF to UICC) with an oscilloscope. SWP
initialization should be performed during phone startup.
