[ICS][Deodex] stock system apps and framework [2.007.04_COM_GEN1]
This will have to be "flashed" through adb and your a100 needs to be on the newest update.
[STOCK ROM] Official Packages
It's the first link on that post. We can thank vache for that.
All bloatware is still included, also acer's MusicA.odex did not deodex and is included.
$ adb shell
# mount -wo remount /system
# rm /system/app/*
# rm /system/framework/*
# cd /mnt/external_sd/path_to_tar
# busybox tar xvf A100_2.007.04_COM_GEN1_deodex.tar -C /
Permissions should be fine as it is in tar format otherwise:
# chmod 644 /system/app/*
# chmod 644 /system/framework/*
dalvik cache will be about 20MB larger and it should be wiped
# busybox rm /data/dalvik-cache/*
$ adb reboot
It will take a bit longer on the first boot while the cache rebuilds
For anyone that doesn't know deodexing is only useful for creating a ROM/theme.
After any theming of the apps permissions will have to be set and keep the official stock ROM in hand in case of a bootloop.
# chmod 644 /system/app/apk_package
# chmod 644 /system/framework/jar_package
I've been running this for a few days and have had no issues at all.
Using this method we can start building some ROMS. I would suggest using tar and maybe include a small script to flash it.
Let me know if anyone wants a full ROM package as this is only the apps and framework.

 As it turns out MusicA does not work at all, it doesn't even show up in the app drawer. Some guy named Jeff Lee compiled some of the framework wrong. com.acer.android.clearfilib_tablet.jar/C:/Users/Jeff_lee/Desktop/_acer/Jeff/clearfilib_tablet.java will not work. It should be a classes.dex file in the jar archive. Oh well it looks like its fixed in ICS.
Here's Deodex ICS, everything deodexed without issues. But without root this will be useless.  We now have root so this will be very useful
