Hempy,
I really do suggest you have a look at the FAA AIM and acquaint yourself with amongst other things, FAA transponder requirement. Don't take my word for it, get the facts direct. Or the below, if you want the legal words.
14 CFR 91.215 - ATC transponder and altitude reporting equipment and use.
See also: <http://www.faa.gov/documentLibrary/media/Advisory_Circular/AC%2090-114.pdf> particularly Page 8
Simplified, FAA does not provide separation between VFR/VFR or VFR/IFR in E, but may, in a capacity available basis only, provide traffic advisories.
Just go and read it up yourself, in this day and age of the internet, it is so easy.
Clue: Before "alphabet soup" airspace designations, E in US was called "VFR Exempt".
Tootle pip!!
FAA ADS-B mandate --- only aircraft that currently need Mode A/C transponders will require ADS-B by 2020.
