What LLARP can't do
LLARP does a few things very well, but obviously can't do everything.
Anonymize OS/Application Fingerprints
Mitigating OS/Application Fingerprinting is the responsibility of the OS and Applications. LLARP is an Unspoofable IP Packet Onion router, tuning OS fingerprints to be uniform would be a great thing to have in general even outside of the context of LLARP. The creation of such an OS bundle is a great idea, but outside the scope of LLARP. We welcome others to develop a solution for this.
Malware
LLARP cannot prevent running of malicious programs. Computer security unfortunately cannot be solved unilaterally by networking software without simply dropping all incoming and outgoing traffic.
Phoning Home
LLARP cannot prevent software which sends arbitrary usage data or private information to Microsoft/Apple/Google/Amazon/Facebook/etc. If you are using a service that requires the ability to phone home in order to work, that is a price you pay to use that service.
Make Sandwiches
At its core, LLARP is technology that anonymizes and authenticates IP traffic. At this current time LLARP cannot make you a sandwich. No, not even as root.
