I've been trying to meet this professor to talk about whether or not he would like to help me further develop this software that I've released.
We've exchanged emails three times. The last one was from him, about a week ago, telling me that he was busy this past week but might be available this coming week. He ended this email by saying "I will be in touch." I'm not sure if I should take this to mean that he intends on contacting me about his availability, or that he will respond promptly to any email I send him.
On the one hand, I could've slipped from his mind this past week because he is so busy, and I should contact him to remind him of my great interest in his mentor-ship. On the other hand, I don't want to be pushy; he does already have a lot to deal with, after all.
